Suggestion: Add a "Recommended" tab to language discussions where moderators can sticky posts
It's fairly difficult to find things in the discussion board, and the same topics get posted again and again "What is the difference between ser and estar" etc.
It would be nice if there was a place were Frequently Asked Questions and helpful links could be consolidated.
Duo team said they were working on the forum (and a FAQ) and a lot of good ideas, like this one, have been proposed by users. So I guess we just have to wait.
If you have some idea of what should be in an FAQ :http://www.duolingo.com/comment/781395. And you'll see some advise/search engine syntax to do more accurate search.
